Change Appearance. The changeling can use its action to polymorph into a Medium humanoid it has seen, or back into its true form. Its statistics, other than its size, are the same in each form. Any equipment it is wearing or carrying isn’t transformed. It reverts to its true form if it dies.

Dagger. Melee or Ranged Weapon Attack: +5 to hit, reach 5 ft. or range 20/60 ft., one target. Hit: 4 (1d4 + 3) piercing damage.

Whip. Melee Weapon Attack: +5 to hit, reach 10 ft., one target. Hit: 5 (1d4 + 3) slashing damage.

Hand Crossbow. Ranged Weapon Attack: +5 to hit, range 30/120 ft., one target. Hit: 6 (1d6 + 3) piercing damage.

Unsettling Visage (Recharges after a Short or Long Rest). Each creature within 30 feet of the changeling must succeed on a DC 13 Wisdom saving throw or be frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Chevy is adept at giving well-timed assistance; he can take the Help action as a bonus action
